Starbucks Is Selling a $150 Smart Mug That Lets You Control the Temperature of Your Coffee

Device is already buzzy

Watch out, folks, your coffee may soon be getting hacked—in a good way.

A hundred Starbucks stores are selling smart coffee mugs made by Ember. The internet-connected mug lets users adjust the temperature of the liquid inside via the brand's smartphone app. The device has been in the making for several months, but it's going to be fascinating to see whether it takes off.

The Ember mug costs $150, which is more than the $140 Snap Inc. is charging for its video-recording sunglasses, Spectacles. Starbucks is the exclusive distributor of the mug.

So, if there is a precise temperature you prefer your beverages to be, this technology may be your solution. It can rapidly cool your coffee to a Farenheit degree and then hold the temperature right there for as long as the mug is powered.

Ember has an interesting list of investors, including Demi Lovato, Nick Jonas and Ndamukong Suh. Lovato posted the above picture on Instagram before the weekend, and the image has garnered more than 900,000 likes.
